This module is based on g.gui.gcp, the GCP manager of GRASS GIS. It is part of i.ortho.photo suite. The aim of this module is to give absolute location values to the fiducial points present (in number of 4 or 8) in a scanned aerial photo. This is necessary as (manual) scanning introduces distortions, rotations and also may not be limited to scan the boundary of the photo itself. It is thus necessary to give to each fiducial the exact coordinates in mm as given by the aerial photographic instrument design, which is unique per camera. This module requires you to have made a group with your aerial photo (i.group), a camera description file (i.ortho.target) and use them to launch the module. Additional requirements are the order of rectification (1 if no of Fiducials is 4, 2 if no of Fiducials is 8) and an extension file (if not given, defaults to \$filename_ip2i_out) An example for Location imagery60: g.gui.photo2image group=aerial@PERMANENT raster=gs13.1@PERMANENT camera=gscamera order=2 extension=try --o Screenshot of g.gui.photo2image Figure: Screenshot of g.gui.photo2image
